A catch per unit effort - soak time model for the Bristol Bay red king crab fishery, 1991-1997
Postseason commercial fisheries data are used to estimate a catch per unit effort (CPUE) soak time relationship for the 19911993 and 19961997 Bristol Bay red king crab (Paralithodes camtschaticus) fishery in order to gain regulatory and in-season management insight. Use of commercial fishery dat...
